Thursday’s second-to-last of the popular summer concert series at Columbus Park, which included more than a few visits to the event’s “drunk tent,” resulted in three arrests for drunk or disorderly behavior.

The first arrest came after Quentin Brunetti, 19, of Trumbull, tried to escape the so-called drunk tent, where underage drinkers are kept to be picked up by their parents when they are seen to be intoxicated.

Sgt. Kelly Connelly said Brunetti was escorted out of the venue for misbehaving and, when he tried to sneak back in, he was detained by concert personnel and brought to the tent.

He asked to go to the bathroom just before 7 p.m. and, as an officer escorted Brunetti and another youth back from the toilet, he made a break for it. He ran to a fence and began climbing it, but the officer was able to pull him down and two off-duty New Haven police officers stepped in to help get handcuffs on him.

Brunetti suffered a cut to one of his pinky fingers and the Stamford officer injured his forearm in the struggle.

Connelly said he was charged with disorderly conduct and resisting arrest, and released on a promise to appear at court. Police called his father in Trumbull and was told to “Please, come get him,” she said

Capt. Tom Wuennemann said that there were seven youths at Thursday night’s Sister Hazel concert, attended by about 3,500 revelers, who had to be taken to the hospital or had their parents called to take them home. At the Andy Grammer concert the week before, attended by 6,500 people, there were 27 youths either detained in the drunk tent or taken to the hospital. Wuennemann said the crowd at the Grammar concert was much younger than those who attended Sister Hazel’s.

The second arrest on Thursday, a little after 9 p.m., happened after an officer was flagged down by a woman working at Alive@Five, who said a man had poured a beer all over her. Police found Brent Rodney, 21, of Linwood Lane, Stamford, near the Black Bear Restaurant and he was identified by the woman as the one who drenched her with beer.

The woman told police Rodney first asked her take a picture of him, but then became abusive and began yelling. After the woman told him to leave the venue, she said he pushed her and poured his beer all over her. Rodney was charged with breach of peace and was also released on a promise to appear at court on Aug. 20.

In the third incident, just before midnight, Connelly said a bouncer at the Glamour Restaurant and Lounge was having trouble escorting a Sandy Hook woman out of the bar because she appeared drunk and was bumping into and arguing with other patrons.

A nearby police officer was called to remove the woman, Brianna Engelke, 20, but she would not budge from the bar’s entrance on West Park Place, Connelly said.

Connely said Engelke became very combative and began flailing her arms while refusing to obey the officer’s directions. Two other officers had to come to the bar before they were able to get her into handcuffs and into the rear seat of a waiting cruiser. At the police station, she was so combative and uncooperative, police were unable to process her, so they put her into a cell to dry out for the night, Connelly said.

Engelke was charged with breach of peace and resisting arrest.

In addition Thursday, cops also arrested an alleged drunk driver who attended Alive@Five Thursday night. Wuennemann said Dominique Chisenga, 22, of Seaton Road, Stamford, was pulled over by Lt. Diedrich Hohn in a Washington Boulevard parking lot. He was charged with driving while under the influence, no insurance, driving under suspension and no registration.
